Effect of metoprolol on caspase-9 expression following coronary microembolization (CME). A The relative protein levels of procaspase-9 and activated caspase-9 were determined using Western blots (normalized to glyceraldehyde-3-phosphate dehydrogenase [GAPDH]). Lanes 1, 2, 3 and 4 in the representative gel show caspase-9 expression in the control, CME (after 6 h), metoprolol and Z-LEHD-FMK (ZLF) groups, respectively. B Bars (n=10) represent mean ± SD. *P<0.05 compared with the control group; ^#P<0.05 compared with the CME group
